SUPPORTING-BRACKET.

LSQAS.

Application led November 18, 1912.

To @ZZ whom/15 may concern Be it known that I, li-inns It. SMITH, acitizen of the United States, residing at Mechanicsville, county ofSaratoga, and State of New York, have invented certain new and usefulimprovements in Supporting-Brackets, of which the following is a.specihlcation.

This invention relates to supporting brackets.

My invention has for its object the provision of a novel supportingbracket for the expansion tanks of hot water heating systems and forkitchen range boilers which can be quickly and easily secured to thewall or any other suitable support or object and will be adapted toclamp and support, without requiring the use of other means, the lowerflanged end of the tank or boiler, enabling the tank or boiler to bereadily set or positioned at any desired point and height.

1n carrying out the invention, 1 provide a back plate having membersadapted to cooperate with the edge of the tank or boiler end and ofnovel construction, and a clamp and adjusting means therefor cooperatingwith the back plate in a new manner and with it adapted to support andclamp the flange on the end of the tank or boiler whether the latter beof the riveted or electrically welded type.

The preferred embodiment of the invention is set forth hereinafter andthe novel features of the device are recited in the appended claims.

In the accompanying drawings Figure 1 is a plan view, dotted linesshowing a portion of a tank or boiler flange; Fig. 2, a vertical sectionon line 2 2, Fig. 3, showing the boiler' flange in full lines,illust-rating how the boiler is clamped and held in position; Fig. 3, afront view of the complete bracket; Fig. 4l, a det-ail View of the backof the back plate; Fig. 5, a detail perspective, looking toward theinner face of the clamp; and Fig. 6, a detail perspective of one of thelugs on the back plate and the screw.

The metallic back plate 1 is flat on its rear surface so it will liefirmly and evenly against the wall or studding or other support to whichit is to be connected, being provided with holes 2 for the reception ofscrews or other fastenings by which it is fastened to the wall. Formedintegral with the plate 1 is a shelf 3 which has a notched or recessedpart 4 and beneath which is a solid support- Specification of LettersPatent.

ing brace 5 through which extends an aperture 6 communicating with a`square shaped recess 7 in the rear of the plate 1 which receives andprevents from turning the head of a bolt 8 whose shank extends throughthe hole 6, The head of the bolt is prevented from backward movement onaccount of lying' against the wall to which the back plate is fastenedand consequently, the head of the bolt is always retained in the recess7 and the bolt is prevented from turning.

At 9 is shown a clamp which has a somewhat elongated opening 10 in itsshank for the recept-ion of the bolt 8 and there is provided a nut 11which bears against the shank 12 of the clamp and by which said clampmay be adjusted and made to engage the tank or boiler with any desiredpressure. To prevent twisting or sidewise displacement of the clamp, itsshank 12 is received in the recessed part t of the shelf and to afford afulcrum to permit the tilting adjustment of the clamp, its shank isprovided with a flange 13 which bears against the strengthening brace 5.lThe brace 5 not only trusses or braces the shelf 3 and thus takes upthe weight of the tank or boiler and its contents, but it forms a solidabutment or bearing to take up the pressure exerted by the flange 18when the nut 11 is tightened.

To increase the extent of the bearing or clamping surface engaged withthe ange of the boiler or expansion tank, the relatively wide head 14 isprovided on the clamp 9 and the inner face thereof is provided withseparated bearing lugs 15.

On the back plate 1 are lugs 16 which are spaced apart a distancegreater than the length of the head 14; these lugs being provided withrounded surfaces 17 which begin at the points 18, farthest from theplate 1 and curve inwardly and downwardly to the points 19 near or atthe surface of the plate 1. This formation being somewhat orsubstantially opposite the general position of the bearing lugs 15, notonly naturally accommodates the curvature of the flange 2O of theexpansion tank or boiler, but enables the clamp head and its lugs toobtain a better grip on the flange of the tank or boiler and to wedge itunder the lugs 16. The tank or boiler rests on the shelf 3 and beinggripped at its inner edge, any tendency it may possess to fall forwardby gravity, tends to more firmly throw and engage its flange with thesaid lugs as it cannot become disengaged from said lugs on account ofthe pressure eX- erted on it by the clamp.

The bac.: plate is provided above the shelf 3 with a screw-threadedopening 21 receiving a flat-headed short screw 22 against which the tankrests whether the latter be electric-ally welded lor riveted, providedthe diameter of the tank is such that it naturally lies away from backplate 1 between the lugs 16, due to its abutting said lugs 16, and inorder to line up the tank or boiler, the screw 22 should be adjusted asdesired so that it will constitute an abutment for the boiler or tankflange. If the boiler or tank is riveted the rivet heads will naturallyrest against the plate 1 and by their engagement with the lugs 15 and 16they prevent any disengagement of the boiler or tank from the support orbracket.

The lower part of the back plate 1 may be provided with openings 23 forthe sake of lightness.

Having thus described my invention, .what I claim as new and desire tosecure by Letters Patent, is

1. In a supporting bracket, the combination with a back plate having ashelf provided with a notch in its front edge, of a clamp having a partthereof received in said notch and which. is adjustable toward the backplate and adapted to clamp an article on said shelf and against the backplate.
